When every i restart a host node, it takes too hard reboots to get the server up.

When i first send the server for a restart this is the start of the log "messages"

However the server starts find and there is no problem.

I have seen some bug reports about a kernel message which sound likely, however it is fixed in a kernel which is not avaliable yet for Centos. Currently using "Linux IS-1672 2.6.18-8.el5.028stab031.1PAE #1 SMP Sat Apr 28 01:22:56 MSD 2007 i686 i686 i386 GNU/Linux"

With most uptodate operating system.

Thanks , Sorry about long post.

Ashley, can you, please, explain your problem more clearly! I just don't understand your problem...
For simplicity, do it in the following way: "I give the command XXX, and I expect YYY to happen, but ZZZ happens" Smile Without any logs for the beginning.

Thank you,
Vasily.

When ever i run the command vzctl restart or vzctl stop with a vps id number it restarts every single vps or stops every single vps.

This sometimes causes the server to Kernel Panic if the VPS have a high load, but normal this just causes every VPS to restart, even if i just run the command vzctl restart 102.

Hmm... Sounds like something fantastic! Wink Can you give me an ssh access to your node?

Thanks,

I am currently requesting a KVM over ip, due the kernel errors, once that it setup if you wish i can give you SSH and KVM access to the node.

Is this ok?

It's very good! There must be a bit more messages above it, concerning EIP register. Can post it too, please!

Thank you,

Hello,

We fixed one important bug related to VE stop and iptables (http://bugzilla.openvz.org/show_bug.cgi?id=561) in 028stab033 kernel. Can you, please, try it and inform us about results?

Thank you,
Vasily.

The kernel error i receive is the screen shot posted above, it happens during the server shutting down, and happens just after all the VPS are shutdown.

Thanks
